Context hints are yellow and green tags with frames that tell you where elements close to the position of the cursor start and end.
Inside an element
A green rectangular tag shows the cursor is inside an element.
Figure 1. The cursor is in the <cmd> element.
Before an element
A yellow opening tag shows the cursor is before an element.
Figure 2. The cursor is before the <cmd> element.
After an element
A yellow closing tag shows the cursor is after an element.
Figure 3. The cursor is after the <cmd> element.
Between elements
Two yellow tags show the cursor is between two elements.
Figure 4. The cursor is between the <context> and the <steps> elements.
Inside a parent element, before/after a child element
When you place the cursor inside an element that has child elements and the cursor doesn't immediately precede or follow any of them, yellow context hints appear to show the beginning and the end of the nearest child element that goes before or after the cursor, or both.
Figure 5. The cursor is in the <para> parent element; the yellow tag shows the <cmd> child element.
In such cases, you can also set the green tag and the frame of the parent element to be shown.
Figure 6. The cursor is in the <para> parent element; the tags show the <para> parent element and the <cmd> child element.
